How to eliminate pesticide residues in fruits and vegetables?

There are several ways to remove pesticide residues from fruits and vegetables. Soak the vegetables and fruits in salted water, peel the vegetables and fruits, blanch the vegetables, and soak the vegetables and fruits in floured water.

There are residual pesticides in vegetables and fruits, and if you want to eat healthy and safe, you must wash vegetables and fruits well. Some people wash vegetables and fruits directly with water, so that they cannot wash away the residual pesticides on vegetables and fruits, and the best way is to add a little salt to the water and then soak them. After a few minutes, the vegetables and fruits are taken out and cleaned, and the residual pesticides can be effectively removed.

Pesticides left on vegetables and fruits are harmful to the body, and if you want to remove them completely, you have to peel them. Vegetables and fruits can be peeled as much as possible, such as eggplant, cucumber, horn melon, loofah, apple, white pear, etc., we have to take the peeler to peel. Peeling and removing pesticides is the most effective and makes us safer to eat.

For example, grapes, oranges, oranges, grapes, etc. can be peeled and eaten directly, and they must be peeled before eating, so that it is safer.

There are many tips in life, in order to better remove the residual pesticides on vegetables, we can use the blanching method. Put water in the pot, boil the water, blanch the washed vegetables in the pot, take them out for 1-2 minutes, quickly cool them, control the moisture and set aside. This method is suitable for green leafy vegetables such as spinach, rape, bok choy, lettuce, etc., as well as vegetables such as broccoli, cauliflower, snow peas, etc.

This method can be used when pesticides are difficult to clean from pesticides left on vegetables and fruits. Add some flour to the water, soak the vegetables and fruits in it, and after a few minutes, you will find that there will be a lot of dirt in the water, and the vegetables and fruits will be washed very clean. You can also put some starch in the water, and then put the vegetables and fruits in to wash, and it will also be clean.

It is not recommended to eat the vegetables and fruits you buy immediately, and it is best to leave them for a day before eating, which can reduce the residue of pesticides.

The use of fruit and vegetable cleaning agents can increase the dissolution of pesticides, so a small amount of fruit and vegetable cleaning agents can be added when soaking. After soaking, rinse it with running water two or three times. Chinese cabbage, cabbage, cabbage and other vegetables, before eating, these vegetables can be broken into leaf by hand, and then soaked in salt water for a period of time, when soaking vegetables, it is best to let each side of the vegetables fully contact the salt water.

Many fruits will have pesticide residues, eating in the human body will be harmful to the body, if you want to eliminate excessive pesticide residues, you should clean the fruit or peel it to eat.

Vegetables and fruits can be soaked in hot water or sterilized in a microwave oven, and light waves can be used to kill insects.

As we all know, there will be some pesticides left on vegetables and fruits, and if you want to completely eliminate them at this time, then you can put vegetables and fruits into the corresponding pots. Add some salt, or add the corresponding detergent, soak for 30 minutes or an hour, and then rinse with water. You can also buy the corresponding vegetable and fruit cleaning equipment, and put the instrument directly into the water.

In order to ensure the freshness and sales rate of vegetables and fruits, many farmers will spray some pesticides on them when planting vegetables and fruits, and the appearance of pesticides can not only make vegetables and fruits grow particularly well, but also make fruits and vegetables particularly healthy and bright. Therefore, such vegetables and fruits must be cleaned in a way, otherwise it is likely to lead to pesticide residues in the food, so they will be eaten into their own bodies. Therefore, for some leafy vegetables, such as spinach, leeks, lettuce, bok choy, etc., be sure to rinse with water first, then soak in water for 10 to 20 minutes, add a small amount of fruit and vegetable cleaning agent, and then rinse with water 3 or 4 times repeatedly.

In this way, the vegetables and fruits can be cleaned very cleanly, and there is no need to worry about some stubborn pesticides remaining in the vegetables and fruits. In addition, like some vegetables and fruits with skin, most of the pesticides are stored on the skin, so when eating, try to peel off the outer skin, which is not only the easiest way to remove pesticides, but also to ensure that the fruit inside is very healthy and hygienic. In addition, you can also put the vegetables and fruits you bought back in the refrigerator and freeze them for a period of time, so that the pesticides outside the vegetables can be effectively decomposed accordingly, so that you can clean them again.

Finally, I would like to say that these pesticides, including some insects, are more afraid of high temperatures, so put the cleaned vegetables into a pot of cold water, turn on the high heat, heat them, and cook the vegetables two or three times over and over again, and the vegetables will become very clean. In addition, the boiled vegetables should also be rinsed with water, otherwise they will be contaminated with some impurities. I believe that through the introduction, everyone can clearly grasp these three methods, so you can pick a method to clean, which can ensure that the washing is particularly clean.

To fully wash for more than 30 seconds, peel and eat, heating vegetables can degrade pesticides, you can first wash off the impurities on the surface with water, and then soak for half an hour, and then use fruit and vegetable cleaning agents to dissolve pesticides.

Wash with dish soap, wash with water, or wash several times, use special cleaning tools, special cleaning agents, and soak in warm or hot water for a period of time.

You can choose a fruit and vegetable cleaner to wash the fruit, or you can use running water to wash the fruit.

First of all, you can soak these vegetables and fruits in water for a period of time, and sometimes you can also add some salt, and then soak for about an hour to remove them.

Before use, you can soak it in water for about 1 2 hours, so that the residual pesticide can also be removed.

We can buy some special fruit and vegetable cleaners, use these cleaners to wash the fruit, and be sure to wash it with running water.

A large number of pesticides remain on vegetables and fruits, if not cleaned, long-term consumption, the damage to people's bodies is very great, so how to remove the residual pesticides on vegetables and fruits? See below.

1. Water soaking washing method: mainly used for leafy vegetables, such as spinach, lettuce, cabbage, etc. Generally, rinse off the dirt on the surface with water first, and then soak it in water for about 10 minutes.

If necessary, a certain amount of fruit and vegetable cleaning agent can be added to make the pesticide dissolve. Washing and soaking 2 or 3 times in this way can basically remove most of the residual pesticide components.

2. Alkaline water immersion cleaning method: most organophosphorus insecticides can be quickly decomposed in an alkaline environment, so soaking in alkaline water is one of the effective methods to remove vegetable pesticide residue pollution. Add 5 10 grams of edible alkali to a milliliter of water to prepare alkaline water, and put the vegetables after preliminary rinsing into alkaline water (according to the amount of vegetables with enough alkaline water).

After soaking for 5 to 10 minutes, rinse the vegetables with water, repeating the rinse about 3 times for better results.

3. Cleaning and peeling method: For vegetables with skin such as cucumbers, carrots, winter melons, pumpkins, eggplants, tomatoes, etc., you can use knives to peel off the skin containing residual pesticides, and only eat the fleshy part, which is both delicious and safe.

4. Heating cooking method: carbamate insecticides will decompose faster with the increase of temperature. Therefore, for some vegetables that are difficult to handle by other methods, some residual pesticides can be removed by heating.

The above is an introduction to the method of removing pesticide residues from vegetables and fruits.

Leafy vegetables can be washed with soaking water. You can first rinse off the surface dirt with water, and then soak it in water for less than 10 minutes.

Because the pesticide varieties of polluted vegetables are mainly organophosphorus insecticides, which are insoluble in water, fruit and vegetable cleaning agents can be added to promote the dissolution of pesticides when soaking, and rinse with water after soaking.

Alkaline water immersion removes organophosphate insecticides. Organophosphate insecticides decompose quickly under alkaline conditions, and soaking vegetables in alkaline water for 5 to 15 minutes will effectively remove residual pesticides.

Fruit vegetables can be peeled. Vegetables such as tomatoes and eggplants have a layer of wax on the surface, and after spraying pesticides, there are more residual pesticides on the surface, and peeling off the skin can effectively remove the residual pesticides.

Now fruits and vegetables contain pesticides, first of all, we must know how to choose fruits, recently I found a version of the kiwifruit tips, the right of its pointed part, the more flat the better, to choose the sharp kind, in addition to fruits, like apples This skin is more nutritious, you can soak it, go to pesticides, the general tap water blister washing is not very effective, my mother is using oxygen to wash the fruit, degrading pesticides, and there is no residue, don't worry about eating the detergent, You can also pay more attention to it.

It is useful to put some alkaline noodles or some salt in the process of washing fruits. Especially grapes and apples, strawberries, etc.

Now it is much better, the large comprehensive market will be preliminarily tested and then in batches under the farmers' market, soak for half an hour before use, and then rinse with water to remove 90% of the pesticide residues, the pesticide residues inside the fruits and vegetables themselves are less, and do not affect the health of the body.

Answer: (1) Running water rinsing plus soaking method. The main pesticides used to contaminate vegetables are organophosphorus insecticides.

Organophosphate insecticides are insoluble in water, and this method can only partially remove pesticide contamination. However, washing is the basic method of removing other dirt and removing residual pesticides on vegetables and fruits, and is mainly used for leafy vegetables, such as spinach, enoki, leek flowers, lettuce, bok choy, etc. Generally, the surface dirt is rinsed off repeatedly with water, then soaked in water for 15 minutes, and then rinsed with running water two or three times.

Fruit and vegetable cleaning agent can increase the dissolution of pesticides, and a small amount of fruit and vegetable cleaning agent can be added when rinsing.

2) Running water rinsing and alkaline water immersion method. Organophosphate insecticides decompose rapidly in an alkaline environment, so this method is an effective measure to remove pesticide contamination. It can be used for all kinds of vegetables and fruits.

The method is to rinse the surface dirt first, soak it in alkaline water (generally add 5 to 10 grams of alkaline surface to 500 ml of water) for 5 to 15 minutes, and then rinse with water 3 to 5 times.

3) Peeling method. The amount of pesticides on the surface of vegetables and fruits is relatively large, so peeling is a better way to remove residual pesticides. It can be used for apples, pears, kiwis, cucumbers, carrots, winter melons, pumpkins, zucchini, eggplants, turnips, etc.

4) Storage method. During storage, pesticides can be slowly decomposed into substances that are harmless to humans. For fruits and vegetables that are easy to preserve, they can be stored for a certain period of time with less pesticide residues.

It is suitable for non-perishable species such as pumpkin and winter melon. Generally, it is stored for more than 15 days. At the same time, it is recommended not to eat freshly picked, unpeeled fruits and vegetables immediately.

5) Heating method. Carbamate insecticides decompose faster as the temperature increases. Therefore, some vegetables and fruits that are difficult to treat by other methods can be removed by heating.

It is often used in celery, spinach, bok choy, cabbage, green pepper, cauliflower, beans, etc. Wash the surface dirt with clean water, put it in boiling water for 2 to 5 minutes to remove it, and then wash it once or twice with clean water.

Hello, we have a professional pesticide residue, paraffin antibiotics, is one of the research results of the national 863 program, but also the Olympic Games designated guarantee products, safety please rest assured,

1. For all leafy vegetables, the best way to remove pesticide residues is to soak them in water, and you can also add some fruit and vegetable cleaning agents to the water.

Alkaline water immersion method. Soaking fruits and vegetables in alkaline water for 5 to 15 minutes can remove organophosphorus pesticides on the surface of fruits and vegetables. But after soaking, be careful to rinse the alkaline water.

Storage. The oxygen in the air has the effect of decomposing some pesticides. Therefore, some vegetables and fruits that can be stored can be stored for 1 3 days before eating by extending the storage time, so as to reduce the toxicity of some pesticide residues.

Heating method. Some pesticides are afraid of alkali and heat, and high temperatures can help speed up the decomposition of pesticides. Boil vegetables in boiling water for 2 5 minutes to remove some pesticide residues.

Peeling method. Because pesticide residues are basically on the surface of vegetables and fruits, although peeling off the skin will lose some nutrients, it is very effective for removing pesticide residues.

Soak in water and wash method. For leafy vegetables, a better way to remove pesticide residues is to soak them in water. You can also add some fruit and vegetable cleaning agent to the water to accelerate the dissolution of pesticides.
